Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.

What are the signs that a double replacement reaction has occurred?

Back

Formation of a precipitate, gas, or water; color change; or temperature change.

Front

What is a precipitate in the context of double replacement reactions?

Back

A precipitate is an insoluble solid that forms when two solutions are mixed.

Front

What is the role of solubility rules in predicting double replacement reactions?

Back

Solubility rules help determine whether a product will be soluble or form a precipitate.
